The latest trailer for small-screen Batman spin-off Gotham has revealed some of the caped crusader’s adversaries before they were famous.

Featured in the teaser for the Warner Bros-produced show, we catch glimpses of a young Poison Ivy, The Penguin (pictured), Catwoman and The Riddler.

The series will draw on the origin story of a pre-Batman Gotham City following the young Commissioner Gordon’s rise through the ranks of the police department and “focus on the unlikely friendship Gordon forms with the young heir to the Wayne fortune” (the just-orphaned Bruce Wayne) in the days of the city before the Dark Knight rises.

Ben Mckenzie (The O.C.) is the young Detective James Gordon (played by Gary Oldman in the Christopher Nolan trilogy) and the cast also includes Donal Logue (Sons Of Anarchy) as Gordon’s partner, Harvey Bullock.

Also starring Jada Pinkett Smith as the town’s crimelord Fish Mooney and Sean Pertwee (Elementary) as Bruce Wayne’s butler Alfred, the series will see Gordon navigate the layers of corruption that secretly rule Gotham City – the spawning ground of the world’s most iconic villains, the larger-than-life personas who would become Catwoman, The Penguin, The Riddler, Poison Ivy, Two-Face and The Joker.

From producer/writer Bruno Heller (The Mentalist, Rome) Gotham premieres in the US on September 22 and will air in the UK on Channel 5 and Demand 5 this autumn.
